I can’t choose either tanks or ships, what should I do?
Steam version.
Click this under the To Battle button and change to a mode that allows tanks or ships.
Then you’ll be able to place the vehicles in your lineup as you have been doing with planes.
Well that makes a difference… Need more info @ShkekN1 , when did this start happening and are you seeing the modes under the button.
It could be as simple as having the filter enabled for just planes in the vehicle select button in the tool bar.
